magnet will he silenced by the novel cushioning means presented.

Another object of importance of the inven- 115 tion is to provide such a device in which the working elements thereof are readily accessible in the event of replacement or repair becoming necessary. Another object resides in providing a beating unit for'vacuum cleaners, wherein the beater will rapidly engage the material being cleaned, in short successive impacts, so as to loosen the dirt therein without any possible damage thereto. 26 Numerous other objects and advantages of the invention will be realized after a'consideration of the following specification and claims.

In the drawing Figure 1 represents a front elevation of the novel construction in partial sectional view, and disclosing the same with the front cover plate removed.

Fig. 2 re resents a vertical sectional view of the houslng, and nozzle construction, the same disclosing the various details in retracted position. 4

Fig. 3 represents a horizontal sectional view through the housing containing the electro-magnet, and discloses a top view of the same. I

Fig. 4 discloses a perspective view of the beater element.

Now for a more specific descriptionofthis invention, reference is made to the drawing, wherein like numerals designate like parts.

The construction comprises a casting generally referred to by the numeral '1, and consists of a curved pipe section 2 flared at its forward portion 3, and bent downwardlyat 1928. Serial No. 282,940.

its forward end to provide an elongated transversely extending nozzle 4.

Constructed above the flared portion 3 of the pipe 2, is a substantially rectangular vertically disposed housing 5. The front side of the nozzle 4, as well as the front side of the housing 5, is open and is adapted to be closed by an elongated cover plate 6, secured to the housing and nozzle portions of the casing 1, by suitable'screws 7. 69 The top portion of the pipe 2, forms a flooring 8 for the housing 5,'and upon which an electrical magnetic unit or relayv 9 is mountedin vertical disposition. This unit is of the two-coil type, and has arranged upon its top end, an elongated plate 10. At the ends-of the inner longitudinal edge of the plate 10, an upstanding gear 11, is formed for pivotally supporting an armature member 12, in proper magnetic relation to the cores of the coils. Y I

' In Fig. 4 of the drawing, there is disclosed a heater member 13,-consisting of an'elongated bar 14, provided with a triangular shaped frame 15, secured by its apex, to the lower end of said bar. The triangular frame portion 15 is operable within the nozzle portion 4 of the pipe 2, while the elongated bar 14 is slidable within the housing 5, through an opening in theflooring 8. As is disclosed in Fig. 2 of the drawing, the armature 12 is provided with a bifurcated plate extension16, between the furcations of which, the upper end portion of the bar 14 is pivotally connected. A coiled spring 17 connects the top end of the bar 14, to the top wall of the housing 5, for tensionallysupporting the bar.

Secured transversely upon the top sideof the armature 12, is a spring strip 18, disposed obliquely upwardly,'at its free end portion. This free end portionis provided at itstop side with suitable means. for supporting a carbon contact 19. An upstanding arm 20 rigidly secured to the plate 10 at its lower end, is bent outwardly at its upper end and provided with suitable means for supporting a depending carbon contact 21, in opposed respect to the contact 19.

A set screw 22, threaded through the top of V Y memes the honsing h, is adopted to en ege the end portion the em 26, for efijusting the upper contest 21, p

The 239 end the ermeture M, ore properly insnleted i'om each other, while snit able conductors 23, supply current to the coils. f v in operation, at suiteble switch may he employed for cutting on the current to the mognetic device, which result in the vibratingoi the armature 12, end the intermittent opening and closing oi? the coil circuit, by the contacts 19 end 21. The upward and down- Ward movement of the armature l2, transmits e reciprocatory movement to the her it. The pin member 24': is supported by the nozzle 4%, end the-cover plate 6, and hes errenged thereon, a cushionmemloer 25.

This cushioning member is disposed Within the triangular frame 15, of the heater member, sothet the downward movement of the same will he cushioned by the engagement oi the cushion member with the bight portion of the triangular frame, Whereas the upward 25 movement thereof, will likewise be cushioned by the engagement-o f the cushion member with the base section of the freme.

The vibrations oi the armature will transmit rapid impact movements to the triangular 15 obviously loosening dirt and foreign matter on the meteriel, such as the carpet, automobile seats, or the like being cleened.

He ring thus described my invention, what I claim es new is:

1.. in e cleaner of the character described comprising a suction nozzle, 2, Vibratory unit carried by said nozzle, 2, beeter within, said nozzle, shank extending vertically from the so heater, s connection between the shank end said Vibratory unit, said heater being providecl with an opening, and a shock absorbing member connecting with thenozzle end disposed Within the opening to limit the movement or said heater.

2. A cleaner or" the character described comprising a suction nozzle, e beater mounted within the nozzle, said heater comprising an inverted Y-sheped member, a bar connecting the diverged leg portions thereof at their ends, said nozzle being provided with an opening in the upper portion thereof through which the upstanding portion of the Y-shaped-member can protrude and a, vibratory. unit mounted on the nozzle and connected with the upstanding portion of the Y-shaped member for vibrating the said member to intermittently engage the said bar with the surface to be cleaned.

In testimony whereof'I aifix my signature.
